Currently, with the needs of people for speed, delay, high mobility, energy efficiency and the diversification and complexity of services in future life, the 3GPP International Organization for Standardization has started the development of 5G. Typical network coverage is wide LTE coverage and isolated island coverage mode of NR, as it is difficult to achieve full NR coverage with the initial placement of NR. Moreover, a large amount of LTE is arranged below 6 GHz, and the spectrum below 6 GHz available for 5G is very small. Therefore, NR has no choice but to study spectral applications above 6 GHz. However, the high frequency band has limited coverage and fast signal attenuation. In addition, in order to protect the LTE investment in the initial stage of the mobile operator, an operation mode in which the weight interworking is performed between LTE and NR has been proposed.

For example, user devices such as mobile phones are designed on the basis of bands in RF design, but in some band combinations, the number of antennas available to the UE is different, ie one or one. There can be two. If the antenna usage status and resource allocation status on the network side and the UE side cannot be matched, there may be a problem with communication performance.

In order to understand the features and technical contents of the examples of the present invention in more detail, the embodiments of the examples of the present invention will be described in detail below with reference to the drawings, and the attached drawings are for reference and explanation only. However, the embodiment of the present invention is not limited.

Example 1
An embodiment of the present invention provides a method of indicating the number of transmit ports of a user device (UE), which is applied to a UE and is as shown in FIG.
When the current band combination is a band combination having a performance deterioration situation, it is determined whether or not there is a performance deterioration situation in the combination of the current frequency point and the bandwidth, and the determination result is acquired in step 101. ,
Based on the determination result, the step 102 of determining that the UE instructs the network side to use the transmission port of the first quantity or the second quantity larger than the first quantity is included.

Here, the second quantity is the quantity of all transmission ports (Tx) provided in the UE, for example, usually two, and the first quantity is a positive integer quantity less than the second quantity, for example, one. obtain.

The band combination may be a combination of bands of different systems, i.e., one combination may typically include at least two bands, eg, a band combination is a band of one LTE system, and The band combination 2 may include the band of one NR system, and if at least one band is different in the different band combinations, that is, if the band combination 1 includes the LTE band 1 + the NR band 1. The LTE band 1 + NR band 2 may be included, and the band combination 3 may include the LTE band 3 + NR band 3.

Whether or not there is a performance deterioration in the current band combination may be preset by the UE side or may be collectively obtained by the UE side in the long-term use process. , This embodiment does not limit it.

Further, in a band combination having a performance degradation situation, when communicating in a specific area (for example, in a specific cell), the UE usually communicates only on the channel or frequency point corresponding to the cell. At this time, the communication status at the frequency point and the corresponding bandwidth is not the status of performance degradation, and therefore communication can be performed using the most transmission ports.

Hereinafter, the steps will be described in detail based on different examples.

Example 1
Before executing step 101, after the UE enters the connected state, the radio capability is transmitted to the network side.

The radio capability includes performance degradation instruction information in at least one band combination of the UE, the band combination includes at least two bands, and the performance degradation instruction information is a performance degradation situation in the corresponding band combination. It is for indicating whether or not there is.

Alternatively, the radio capability includes the number of transmit ports used by the UE in at least one band combination, and the band combination includes at least two bands.

For example, the performance degradation due to the IMD (intermodulation distortion) problem may cause the performance degradation of the UE.

That is, in the dual connection scene, the band combination of the two systems may cause the deterioration of the characteristics of the UE. In this case, the radio capability indicates the performance deterioration of each band combination in the EN-DC scene of the UE. If there is a performance degradation problem, the instruction is true, 1 TX is used by default, and if not, the instruction is not reported.

Alternatively, it directly instructs to use the 1Tx instruction in a certain band combination.

Further, after reporting the wireless capability to the network side, the network side transfers all the capability information to the CN and saves it accordingly. When the UE enters the connected state again, the network side can directly acquire the radio capability information of the UE from the CN side without depending on the report by the UE.

It is assumed that the UE reports the radio capability information of the UE to the network side and stores it in the CN. The UE acquires the frequency point and bandwidth information of the cell in the cell.

Further, the UE acquires the frequency point and bandwidth information of other cells of the EN-DC after acquiring the configuration information regarding the EN-DC.

Based on this, the network may query the 2Tx capability information of the terminal channel allocation in a certain BC situation, i.e., before executing step 101, the network side suffers from a degradation of the UE's current bandwidth combination. The UE may be actively queried when it is determined that it is a circumstantial bandwidth combination and the frequency points and bandwidths corresponding to the UE's current cell are determined, thereby the frequency points and bandwidths. It also includes a step to get the presence or absence of a UE performance degradation situation in combination.
Correspondingly, the UE executes step 101 when receiving the inquiry.

It should be noted that receiving an inquiry from the network side is one of the embodiments, but other embodiments may be actually adopted. For example, the UE knows the frequency point and bandwidth of the current cell. It may be actively executed later, and if the current band combination is a band combination having a performance degradation situation, it is determined whether or not there is a performance degradation situation in the current frequency point and bandwidth combination. And get the judgment result.

Further, in the step 102, it is determined that the UE instructs the network side to use the transmission port of the first quantity or the second quantity based on the determination result.
If the determination results indicate that there is no performance degradation with the current frequency point and bandwidth combination, then a further step is instructed the network side that the UE should use a second quantity of transmit ports. Including.

That is, if there is a performance degradation problem with the currently configured band combination, the UE further determines if there is a performance degradation problem with the current frequency point and bandwidth combination, otherwise the UE will RRC. The connection reconfiguration completion message indicates that 2TX is supported. If not, do not instruct.

As can be seen from the above description, when the wireless environment changes, the UE determines whether or not there is a performance degradation situation in the band combination in the current environment and the combination of the frequency point and the bandwidth. For example, if the UE has already determined the number of transmit ports used in the previous cell, but the EN-DC configuration changes or the environment changes (eg, approaches the cell center) while the UE is moving, the UE The currently configured band combination determines if there is a performance degradation problem, and if so, the UE further determines if there is a performance degradation problem with the current frequency point and bandwidth combination. If so, the response message tells you to support 2Tx.

Finally, in this example, when the UE reports the quantity of the supported transmit port (Tx) to the network side via the secondary cell group SCG SRB, the base station of the secondary cell group reports the quantity to the primary of the UE. It is transmitted to the base station side where the cell group is located, that is, the SN transfers the TX quantity to the MN by Xn.

Example 2
Before executing step 101, the step of receiving the configuration information transmitted from the network side and including the band combination and / or the combination of the frequency point and the bandwidth, and
Based on the configuration information, the band combination and / or the combination of the frequency point and the bandwidth, a step of determining a supported first quantity transmission port or a supported second quantity transmission port may be included. ..

That is, first, the network transmits a possible Band Communication or Channel Allocation configuration, that is, the network side transmits the bandwidth combination status corresponding to all the cells currently managed, and the bandwidth and bandwidth combination status. And
Based on the received list, the UE marks by Capability which ones support only the first quantity 1Tx and which absolutely supports the second quantity 2Tx, and then marks the first quantity and the second quantity. Send the feedback information you are doing to the network side.

In addition, the terminal may send a preference to mark that the problematic band can support 2Tx, and the signaling used may be UE auxiliary information.
And when the environment changes (eg, the UE moves), the terminal may send a preference to mark that the problematic band can support 2Tx, and the signaling used is UE auxiliary information. You may.

Similar to Example 1, the terminal preference mark may be transmitted after inquiring the terminal whether the network can support 2Tx, and is transmitted to the network side after the UE itself detects a change. It may be one.

Example 3
The method further includes transmitting to the network side hardware capability information indicating whether the UE can support a second quantity of transmit ports. The hardware capability is support for the 2Tx capability.

Based on the above-mentioned determination result, it is determined that the UE instructs the network side to use the transmission port of the first quantity or the second quantity.
If the hardware capability information indicates that the UE supports a second quantity of transmit ports,
If the determination results indicate that there is a performance degradation situation with the current frequency point and bandwidth combination, it is determined that the UE will instruct the network side to use the first quantity of transmit ports. If not, it includes a step of not instructing the network side the number of transmit ports used by the UE.

The reporting method may be to report whether the UE can support 2Tx in the current environment, eg, only 1Tx, by dynamic RRC signaling, eg UE auxiliary information.
If the UE reports, the network configures based on 1Tx or adjusts the resource allocation, and if the UE does not report, the network configures based on 2Tx.

Example 4
This example is based on the scene where the wireless capability is transmitted to the network side in Example 1.
The method is
After transmitting the radio capability to the network side, a step of determining whether or not the inquiry information of the combination of at least one frequency point and the bandwidth transmitted from the network side has been received, and
When the inquiry information of the combination of at least one frequency point and the bandwidth transmitted from the network side is received, the combination of the at least one frequency point and the bandwidth is the transmission port of the first quantity or the second quantity. Further includes, with the step of sending to the network side to support.

The terminal first reports the capability based on the band combination, and after the network receives the report from the terminal, the terminal needs to further report on the capability based on some or some band combinations and having a granularity of channel. Further indicate whether or not.

As can be seen from the above, according to the above technical proposal, communication is performed using the first quantity or the second quantity transmission port in the current environment according to the UE performance situation in the bandwidth combination and the frequency point bandwidth combination. It can be confirmed that the network side is instructed to do this. In this way, the network side can acquire the performance of the UE in the current environment, thereby determining the resources to be allocated to the UE based on the communication performance, and thus the communication performance of the UE can be ensured.

Example 2
An embodiment of the present invention provides a method of indicating the number of transmit ports of a user apparatus (UE), which is applied to a network apparatus and transmits from a UE when the current bandwidth combination is a bandwidth combination having a performance degradation situation. A step of acquiring the given instruction and determining that the UE uses a first quantity or a second quantity of transmission ports larger than the first quantity by the instruction.

Here, the network device may be a base station that manages the UE, and when the UE can connect to two networks, for example, when connecting to a primary cell group and a secondary cell group, one of them. The base station may be, and the primary cell group and the secondary cell group here may be LTE cells and NR cells, respectively. In the optimal embodiment, the network device may be a base station in the primary cell group (ie, LTE cell).

Here, the second quantity is the quantity of all transmission ports (Tx) provided in the UE, for example, usually two, and the first quantity is a positive integer quantity less than the second quantity, for example, one. obtain.

The band combination may be a combination of bands of different systems, i.e., one combination may typically include at least two bands, eg, a band combination is a band of one LTE system, and The band combination 2 may include the band of one NR system, and if at least one band is different in the different band combinations, that is, if the band combination 1 includes the LTE band 1 + the NR band 1. The LTE band 1 + NR band 2 may be included, and the band combination 3 may include the LTE band 3 + NR band 3.

Whether or not there is a performance deterioration in the current band combination may be preset by the UE side or may be collectively obtained by the UE side in the long-term use process. , This embodiment does not limit it.

Further, in a band combination having a performance degradation situation, when communicating in a specific area (for example, in a specific cell), the UE usually communicates only on the channel or frequency point corresponding to the cell. At this time, the communication status at the frequency point and the corresponding bandwidth is not the status of performance degradation, and therefore communication can be performed using the most transmission ports.

Hereinafter, the steps will be described in detail based on different examples.

Example 1
After the UE enters the connected state, it is determined whether or not the wireless capability corresponding to the UE is stored on the core network side, and if not, the request information for acquiring the wireless capability is transmitted to the UE. To do.

The radio capability includes performance degradation instruction information in at least one band combination of the UE, the band combination includes at least two bands, and the performance degradation instruction information is a performance degradation situation in the corresponding band combination. It is for indicating whether or not there is.

Alternatively, the radio capability includes the number of transmit ports used by the UE in at least one band combination, and the band combination includes at least two bands.

For example, the performance degradation due to the IMD (intermodulation distortion) problem may cause the performance degradation of the UE.

That is, in the dual connection scene, the band combination of the two systems may cause the deterioration of the characteristics of the UE. In this case, the radio capability indicates the performance deterioration of each band combination in the EN-DC scene of the UE. If there is a performance degradation problem, the instruction is true, 1 TX is used by default, and if not, the instruction is not reported.

Alternatively, it directly instructs to use the 1Tx instruction in a certain band combination.

Further, after reporting the wireless capability to the network side, the network side transfers all the capability information to the CN and saves it accordingly. When the UE enters the connected state again, the network side can directly acquire the radio capability information of the UE from the CN side without depending on the report by the UE.

It is assumed that the UE reports the radio capability information of the UE to the network side and stores it in the CN. The UE acquires the frequency point and bandwidth information of the cell in the cell.

Further, the UE acquires the frequency point and bandwidth information of other cells of the EN-DC after acquiring the configuration information regarding the EN-DC.

Based on this, the network may query the 2Tx capability information of the terminal channel allocation in a certain BC situation, that is, the network side is a band combination in which the current band combination of the UE has a performance degradation situation. The UE may be actively queried when the frequency point and bandwidth corresponding to the current cell of the UE are determined, thereby degrading the UE performance in combination with the frequency point and bandwidth. Get the presence or absence of the situation.

It should be noted that receiving an inquiry from the network side is one of the embodiments, but other embodiments may be actually adopted. For example, the UE knows the frequency point and bandwidth of the current cell. It may be actively executed later, and if the current band combination is a band combination having a performance degradation situation, it is determined whether or not there is a performance degradation situation in the current frequency point and bandwidth combination. And get the judgment result.

Furthermore, if the received instruction indicates that the UE will use a second quantity of transmit ports, it is determined that there is no performance degradation at the current frequency point and bandwidth combination corresponding to the UE. To do.

That is, if there is a performance degradation problem with the currently configured band combination, the UE further determines if there is a performance degradation problem with the current frequency point and bandwidth combination, otherwise the UE will RRC. The connection reconfiguration completion message indicates that 2TX is supported. If not, do not instruct.

As can be seen from the above description, when the wireless environment changes, the UE determines whether or not there is a performance degradation situation in the band combination in the current environment and the combination of the frequency point and the bandwidth. For example, if the UE has already determined the number of transmit ports used in the previous cell, but the EN-DC configuration changes or the environment changes (eg, approaches the cell center) while the UE is moving, the UE The currently configured band combination determines if there is a performance degradation problem, and if so, the UE further determines if there is a performance degradation problem with the current frequency point and bandwidth combination. If so, the response message tells you to support 2Tx.

Finally, in this example, when the UE transmits an instruction to the network side by the secondary cell group, the instruction transmitted from the secondary cell group is acquired via Xn. Specifically, when the UE reports the quantity of the supported transmission port (Tx) to the network side via the secondary cell group SCG SRB, the base station of the secondary cell group reports the quantity to the primary cell group of the UE. Is transmitted to the base station side where the SN is located, that is, the SN transfers the TX quantity to the MN by Xn.

Example 2
Send configuration information to the UE, including bandwidth combinations and / or combinations of frequency points and bandwidths.
Correspondingly, the UE receives the configuration information transmitted from the network side, including the bandwidth combination and / or the combination of the frequency point and the bandwidth, and based on the configuration information, the UE receives the configuration information. Determine the bandwidth combination and / or the combination of the frequency point and bandwidth, the first quantity of transmit ports to support, or the second quantity of transmit ports to support.

That is, first, the network transmits a possible Band Communication or Channel Allocation configuration, that is, the network side transmits the bandwidth combination status corresponding to all the cells currently managed, and the bandwidth and bandwidth combination status. And
Based on the received list, the UE marks by Capability which ones support only the first quantity 1Tx and which absolutely supports the second quantity 2Tx, and then marks the first quantity and the second quantity. Send the feedback information you are doing to the network side.

In addition, the terminal may send a preference to mark that the problematic band can support 2Tx, and the signaling used may be UE auxiliary information.
And when the environment changes (eg, the UE moves), the terminal may send a preference to mark that the problematic band can support 2Tx, and the signaling used is UE auxiliary information. You may.

Similar to Example 1, the terminal preference mark may be transmitted after inquiring the terminal whether the network can support 2Tx, and is transmitted to the network side after the UE itself detects a change. It may be one.

Example 3
The hardware capability information transmitted from the UE, which is the hardware capability information indicating whether or not the UE can support the second quantity transmission port, is received, and the hardware capability is the support of the 2Tx capability.

When an instruction transmitted from the UE is received indicating that the transmission port of the first quantity is used, resource allocation is performed based on the transmission port of the first quantity.
When the instruction transmitted from the UE indicating that the first quantity transmission port is used has not been received, the resource allocation is performed based on the second quantity transmission port.

The reporting method may be to report whether the UE can support 2Tx in the current environment, eg, only 1Tx, by dynamic RRC signaling, eg UE auxiliary information.
If the UE reports, the network configures based on 1Tx or adjusts the resource allocation, and if the UE does not report, the network configures based on 2Tx.

Example 4
This example is based on the scene where the wireless capability is transmitted to the network side in Example 1.
After receiving the radio capability transmitted from the UE, the inquiry information of the combination of at least one frequency point and the bandwidth is transmitted to the UE.
It is received that the combination of the at least one frequency point and the bandwidth transmitted from the UE supports a first quantity or a second quantity of transmit ports.

That is, the terminal first reports the capability based on the band combination, and after the network receives the report from the terminal, the terminal needs to further report the capability based on some or some band combinations and having a granularity of channel. Further indicate whether or not there is.

As can be seen from the above, according to the above technical proposal, communication is performed using the first quantity or the second quantity transmission port in the current environment according to the UE performance situation in the bandwidth combination and the frequency point bandwidth combination. It can be confirmed that the network side is instructed to do this. In this way, the network side can acquire the performance of the UE in the current environment, thereby determining the resources to be allocated to the UE based on the communication performance, and thus the communication performance of the UE can be ensured.

Example 3
An embodiment of the present invention provides a UE, as shown in FIG.
When the current band combination is a band combination having a performance deterioration situation, it is judged whether or not there is a performance deterioration situation in the combination of the current frequency point and the bandwidth, the judgment result is acquired, and the above judgment is made. Based on the result, the first processing unit 21 that determines that the UE instructs the network side to use the transmission port of the first quantity or the second quantity larger than the first quantity, and
A first communication unit 22 for transmitting the instruction to the network side is provided.

Here, the second quantity is the quantity of all transmission ports (Tx) provided in the UE, for example, usually two, and the first quantity is a positive integer quantity less than the second quantity, for example, one. obtain.

The band combination may be a combination of bands of different systems, i.e., one combination may typically include at least two bands, eg, a band combination is a band of one LTE system, and The band combination 2 may include the band of one NR system, and if at least one band is different in the different band combinations, that is, if the band combination 1 includes the LTE band 1 + the NR band 1. The LTE band 1 + NR band 2 may be included, and the band combination 3 may include the LTE band 3 + NR band 3.

Whether or not there is a performance deterioration in the current band combination may be preset by the UE side or may be collectively obtained by the UE side in the long-term use process. , This embodiment does not limit it.

Further, in a band combination having a performance degradation situation, when communicating in a specific area (for example, in a specific cell), the UE usually communicates only on the channel or frequency point corresponding to the cell. At this time, the communication status at the frequency point and the corresponding bandwidth is not the status of performance degradation, and therefore communication can be performed using the most transmission ports.

Hereinafter, the steps will be described in detail based on different examples.

Example 1
The first communication unit 22 transmits the radio capability to the network side after the UE enters the connected state.

The radio capability includes performance degradation instruction information in at least one band combination of the UE, the band combination includes at least two bands, and the performance degradation instruction information is a performance degradation situation in the corresponding band combination. It is for indicating whether or not there is.

Alternatively, the radio capability includes the number of transmit ports used by the UE in at least one band combination, and the band combination includes at least two bands.

For example, the performance degradation due to the IMD (intermodulation distortion) problem may cause the performance degradation of the UE.

That is, in the dual connection scene, the band combination of the two systems may cause the deterioration of the characteristics of the UE. In this case, the radio capability indicates the performance deterioration of each band combination in the EN-DC scene of the UE. If there is a performance degradation problem, the instruction is true, 1 TX is used by default, and if not, the instruction is not reported.

Alternatively, it directly instructs to use the 1Tx instruction in a certain band combination.

Further, after reporting the wireless capability to the network side, the network side transfers all the capability information to the CN and saves it accordingly. When the UE enters the connected state again, the network side can directly acquire the radio capability information of the UE from the CN side without depending on the report by the UE.

It is assumed that the UE reports the radio capability information of the UE to the network side and stores it in the CN. The UE acquires the frequency point and bandwidth information of the cell in the cell.

Further, the UE acquires the frequency point and bandwidth information of other cells of the EN-DC after acquiring the configuration information regarding the EN-DC.

Based on this, the network may inquire about the 2Tx capability information of the terminal channel allocation in a certain BC situation, and the network side indicates that the current band combination of the UE is a band combination having a performance degradation situation. When confirmed and the frequency point and bandwidth corresponding to the current cell of the UE are determined, the UE may be actively queried, thereby degrading the UE performance in combination with the frequency point and bandwidth. Get the presence or absence of.

It should be noted that receiving an inquiry from the network side is one of the embodiments, but other embodiments may be actually adopted. For example, the UE knows the frequency point and bandwidth of the current cell. It may be actively executed later, and if the current band combination is a band combination having a performance degradation situation, it is determined whether or not there is a performance degradation situation in the current frequency point and bandwidth combination. And get the judgment result.

Further, the first processing unit 21 indicates that the UE uses the second quantity transmission port when the determination result indicates that there is no performance deterioration situation in the combination of the current frequency point and the bandwidth. Instruct the network side.

That is, if there is a performance degradation problem with the currently configured band combination, the UE further determines if there is a performance degradation problem with the current frequency point and bandwidth combination, otherwise the UE will RRC. The connection reconfiguration completion message indicates that 2TX is supported. If not, do not instruct.

As can be seen from the above description, when the wireless environment changes, the UE determines whether or not there is a performance degradation situation in the band combination in the current environment and the combination of the frequency point and the bandwidth. For example, if the UE has already determined the number of transmit ports used in the previous cell, but the EN-DC configuration changes or the environment changes (eg, approaches the cell center) while the UE is moving, the UE The currently configured band combination determines if there is a performance degradation problem, and if so, the UE further determines if there is a performance degradation problem with the current frequency point and bandwidth combination. If so, the response message tells you to support 2Tx.

Finally, in this example, when the UE reports the quantity of the supported transmit port (Tx) to the network side via the secondary cell group SCG SRB, the base station of the secondary cell group reports the quantity to the primary of the UE. It is transmitted to the base station side where the cell group is located, that is, the SN transfers the TX quantity to the MN by Xn.

Example 2
The first communication unit 22 receives the configuration information transmitted from the network side and includes the band combination and / or the combination of the frequency point and the bandwidth, and receives the configuration information.
Correspondingly, the first processing unit 21 is based on the configuration information, the band combination and / or the combination of the frequency point and the bandwidth, the first quantity of transmission ports to support, or the second quantity to support. Confirm the transmission port of.

That is, first, the network transmits a possible Band Communication or Channel Allocation configuration, that is, the network side transmits the bandwidth combination status corresponding to all the cells currently managed, and the bandwidth and bandwidth combination status. And
Based on the received list, the UE marks by Capability which ones support only the first quantity 1Tx and which absolutely supports the second quantity 2Tx, and then marks the first quantity and the second quantity. Send the feedback information you are doing to the network side.

In addition, the terminal may send a preference to mark that the problematic band can support 2Tx, and the signaling used may be UE auxiliary information.
And when the environment changes (eg, the UE moves), the terminal may send a preference to mark that the problematic band can support 2Tx, and the signaling used is UE auxiliary information. You may.

Similar to Example 1, the terminal preference mark may be transmitted after inquiring the terminal whether the network can support 2Tx, and is transmitted to the network side after the UE itself detects a change. It may be one.

Example 3
The first communication unit 22 transmits hardware capability information indicating whether or not the UE can support a second quantity of transmission ports to the network side. The hardware capability is support for the 2Tx capability.

If the hardware capability information indicates that the UE supports a second quantity of transmit ports, the first processing unit 21
If the determination results indicate that there is a performance degradation situation with the current frequency point and bandwidth combination, it is determined that the UE will instruct the network side to use the first quantity of transmit ports. , Otherwise, the network side is not instructed on the quantity of transmission ports used by the UE.

The reporting method may be to report whether the UE can support 2Tx in the current environment, eg, only 1Tx, by dynamic RRC signaling, eg UE auxiliary information.
If the UE reports, the network configures based on 1Tx or adjusts the resource allocation, and if the UE does not report, the network configures based on 2Tx.

Example 4
This example is based on the scene where the wireless capability is transmitted to the network side in Example 1.
After transmitting the radio capability to the network side, the first processing unit 21 determines whether or not it has received the inquiry information of the combination of at least one frequency point and the bandwidth transmitted from the network side.
When the inquiry information of the combination of at least one frequency point and the bandwidth transmitted from the network side is received, the combination of the at least one frequency point and the bandwidth is the transmission port of the first quantity or the second quantity. Send to the network side to support.

The terminal first reports the capability based on the band combination, and after the network receives the report from the terminal, the terminal needs to further report on the capability based on some or some band combinations and having a granularity of channel. Further indicate whether or not.

As can be seen from the above, according to the above technical proposal, communication is performed using the first quantity or the second quantity transmission port in the current environment according to the UE performance situation in the bandwidth combination and the frequency point bandwidth combination. It can be confirmed that the network side is instructed to do this. In this way, the network side can acquire the performance of the UE in the current environment, thereby determining the resources to be allocated to the UE based on the communication performance, and thus the communication performance of the UE can be ensured.

Example 4
An embodiment of the present invention provides a network device, as shown in FIG.
When the current band combination is a band combination having a performance degradation situation, the instruction transmitted from the UE is acquired, and the UE is in the first quantity or a second quantity larger than the first quantity by the instruction. The second processing unit 31 that confirms that the transmission port is used, and
A second communication unit 32 for receiving an instruction transmitted from the UE is provided.

The network device may be a base station that manages the UE, and when the UE can connect to two networks, for example, when connecting to a primary cell group and a secondary cell group, one base station among them. The primary cell group and the secondary cell group here may be LTE cells and NR cells, respectively. In the optimal embodiment, the network device may be a base station in the primary cell group (ie, LTE cell).

Here, the second quantity is the quantity of all transmission ports (Tx) provided in the UE, for example, usually two, and the first quantity is a positive integer quantity less than the second quantity, for example, one. obtain.

The band combination may be a combination of bands of different systems, i.e., one combination may typically include at least two bands, eg, a band combination is a band of one LTE system, and The band combination 2 may include the band of one NR system, and if at least one band is different in the different band combinations, that is, if the band combination 1 includes the LTE band 1 + the NR band 1. The LTE band 1 + NR band 2 may be included, and the band combination 3 may include the LTE band 3 + NR band 3.

Whether or not there is a performance deterioration in the current band combination may be preset by the UE side or may be collectively obtained by the UE side in the long-term use process. , This embodiment does not limit it.

Further, in a band combination having a performance degradation situation, when communicating in a specific area (for example, in a specific cell), the UE usually communicates only on the channel or frequency point corresponding to the cell. At this time, the communication status at the frequency point and the corresponding bandwidth is not the status of performance degradation, and therefore communication can be performed using the most transmission ports.

Hereinafter, the steps will be described in detail based on different examples.

Example 1
After the UE enters the connected state, it is determined whether or not the wireless capability corresponding to the UE is stored on the core network side, and if not, the request information for acquiring the wireless capability is transmitted to the UE. To do.

The radio capability includes performance degradation instruction information in at least one band combination of the UE, the band combination includes at least two bands, and the performance degradation instruction information is a performance degradation situation in the corresponding band combination. It is for indicating whether or not there is.

Alternatively, the radio capability includes the number of transmit ports used by the UE in at least one band combination, and the band combination includes at least two bands.

For example, the performance degradation due to the IMD (intermodulation distortion) problem may cause the performance degradation of the UE.

That is, in the dual connection scene, the band combination of the two systems may cause the deterioration of the characteristics of the UE. In this case, the radio capability indicates the performance deterioration of each band combination in the EN-DC scene of the UE. If there is a performance degradation problem, the instruction is true, 1 TX is used by default, and if not, the instruction is not reported.

Alternatively, it directly instructs to use the 1Tx instruction in a certain band combination.

Further, after reporting the wireless capability to the network side, the network side transfers all the capability information to the CN and saves it accordingly. When the UE enters the connected state again, the network side can directly acquire the radio capability information of the UE from the CN side without depending on the report by the UE.

It is assumed that the UE reports the radio capability information of the UE to the network side and stores it in the CN. The UE acquires the frequency point and bandwidth information of the cell in the cell.

Further, the UE acquires the frequency point and bandwidth information of other cells of the EN-DC after acquiring the configuration information regarding the EN-DC.

Based on this, the network may query the 2Tx capability information of the terminal channel allocation in a certain BC situation, that is, the network side is a band combination in which the current band combination of the UE has a performance degradation situation. The UE may be actively queried when the frequency point and bandwidth corresponding to the current cell of the UE are determined, thereby degrading the UE performance in combination with the frequency point and bandwidth. Get the presence or absence of the situation.

It should be noted that receiving an inquiry from the network side is one of the embodiments, but other embodiments may be actually adopted. For example, the UE knows the frequency point and bandwidth of the current cell. It may be actively executed later, and if the current band combination is a band combination having a performance degradation situation, it is determined whether or not there is a performance degradation situation in the current frequency point and bandwidth combination. And get the judgment result.

Furthermore, if the received instruction indicates that the UE will use a second quantity of transmit ports, it is determined that there is no performance degradation at the current frequency point and bandwidth combination corresponding to the UE. To do.

That is, if there is a performance degradation problem with the currently configured band combination, the UE further determines if there is a performance degradation problem with the current frequency point and bandwidth combination, otherwise the UE will RRC. The connection reconfiguration completion message indicates that 2TX is supported. If not, do not instruct.

As can be seen from the above description, when the wireless environment changes, the UE determines whether or not there is a performance degradation situation in the band combination in the current environment and the combination of the frequency point and the bandwidth. For example, if the UE has already determined the number of transmit ports used in the previous cell, but the EN-DC configuration changes or the environment changes (eg, approaches the cell center) while the UE is moving, the UE The currently configured band combination determines if there is a performance degradation problem, and if so, the UE further determines if there is a performance degradation problem with the current frequency point and bandwidth combination. If so, the response message tells you to support 2Tx.

Finally, in this example, when the UE transmits an instruction to the network side by the secondary cell group, the instruction transmitted from the secondary cell group is acquired via Xn. When the second communication unit reports the quantity of the transmission port (Tx) supported by the UE by the secondary cell group SCG SRB to the network side, the base station of the secondary cell group reports the quantity to the location of the primary cell group of the UE. It is transmitted to the base station side, that is, the SN transfers the TX quantity to the MN by Xn.

Example 2
The second communication unit transmits configuration information including a band combination and / or a combination of a frequency point and a bandwidth to the UE.
Correspondingly, the UE receives the configuration information transmitted from the network side, including the bandwidth combination and / or the combination of the frequency point and the bandwidth, and based on the configuration information, the UE receives the configuration information. Determine the bandwidth combination and / or the combination of the frequency point and bandwidth, the first quantity of transmit ports to support, or the second quantity of transmit ports to support.

That is, first, the network transmits a possible Band Communication or Channel Allocation configuration, that is, the network side transmits the bandwidth combination status corresponding to all the cells currently managed, and the bandwidth and bandwidth combination status. And
Based on the received list, the UE marks by Capability which ones support only the first quantity 1Tx and which absolutely supports the second quantity 2Tx, and then marks the first quantity and the second quantity. Send the feedback information you are doing to the network side.

In addition, the terminal may send a preference to mark that the problematic band can support 2Tx, and the signaling used may be UE auxiliary information.
And when the environment changes (eg, the UE moves), the terminal may send a preference to mark that the problematic band can support 2Tx, and the signaling used is UE auxiliary information. You may.

Similar to Example 1, the terminal preference mark may be transmitted after inquiring the terminal whether the network can support 2Tx, and is transmitted to the network side after the UE itself detects a change. It may be one.

Example 3
The second communication unit receives hardware capability information transmitted from the UE, which indicates whether or not the UE can support a second quantity of transmission ports, and the hardware capability is determined. Support for 2Tx capabilities.

When the second processing unit receives an instruction transmitted from the UE indicating that it uses the transmission port of the first quantity, the second processing unit allocates resources based on the transmission port of the first quantity.
When the instruction transmitted from the UE indicating that the first quantity transmission port is used has not been received, the resource allocation is performed based on the second quantity transmission port.

The reporting method may be to report whether the UE can support 2Tx in the current environment, eg, only 1Tx, by dynamic RRC signaling, eg UE auxiliary information.
If the UE reports, the network configures based on 1Tx or adjusts the resource allocation, and if the UE does not report, the network configures based on 2Tx.

Example 4
This example is based on the scene where the wireless capability is transmitted to the network side in Example 1.
After receiving the radio capability transmitted from the UE, the inquiry information of the combination of at least one frequency point and the bandwidth is transmitted to the UE.
It is received that the combination of the at least one frequency point and the bandwidth transmitted from the UE supports a first quantity or a second quantity of transmit ports.

That is, the terminal first reports the capability based on the band combination, and after the network receives the report from the terminal, the terminal needs to further report the capability based on some or some band combinations and having a granularity of channel. Further indicate whether or not there is.

As can be seen from the above, according to the above technical proposal, communication is performed using the first quantity or the second quantity transmission port in the current environment according to the UE performance situation in the bandwidth combination and the frequency point bandwidth combination. It can be confirmed that the network side is instructed to do this. In this way, the network side can acquire the performance of the UE in the current environment, thereby determining the resources to be allocated to the UE based on the communication performance, and thus the communication performance of the UE can be ensured.
